Re: Bachmann B1

The overall wheelbase sets a fundamental limit. The bogie on earlier LNER Pacifics helped to guide the engine into curves, but Mr Thompson seemed to send his bogies so far enough ahead as to form a scouting party!

Re: Bachmann B1

I'm told the way to assess an A4 model is to note where the valence curve is highest and the r-t-r bodies fail here. They also make some errors on the front view. None of them has so far matched Martin's powers of observation of the smokebox doors either. Even the most exotic r-t-r have the doors f...

Re: Rigid Chassis Locos?

One problem (which also applies to rtr wheels) is the thickness of the wheel and the position of the flange in relation to the front of the wheel. Some of these wheels have a nice spoke profile and this would be lost in turning off the front face. Except the Markits have tyres retained by an interf...

Re: Martin Finney V2

Yes, you'll need to file faces of wheels flush with tyres. They'll still be wider than scale but should fit. You can skim wheels down to the scale 1.85 thickness too if you have the facilities (front flange on tyre should be thick enough - it's usually 0.3) .... Or possibly have bespoke tyres made ...

I'd prefer the Exactoscale profile - the scale half-inch extra clearance each side would be most welcome with outside cylinder locos.

Re: Waisted bearings for Bedford sprung W irons?

If I understand the OP correctly, the washers were introduced to counteract the over-deep cups on the waisted bearings. Thus the axleguard verticality should not be compromised as long as the washers merely take up the slack in the cups. Without the washers, and the resultant play in the cups, the a...
